Which laser parameters are the top influencers in chaotic SL-based systems?

The semiconductor laser with delayed optical feedback continues to be a workhorse for fundamental studies in nonlinear semiconductor laser dynamics. Numerical simulations of this system using a travelling wave model ([1, 2] and references there-in) provide new insights into the impact of key device parameters affecting the chaos bandwidth and spectrum. These suggest that up to a five-fold increase in spectral spread of the chaos, over that demonstrated experimentally to date, might be achievable if semiconductor lasers designed to optimise the chaotic output are fabricated and used. Additionally, connections with prior experimental results are made [3, 4]. An improved fundamental understanding of the chaotic output from this system is achieved.
